Commitment Scheme: Key Derivation and Hash Function
Graph Chatbot
Description
This lecture covers the commitment scheme, key derivation function, pseudorandom generator, and cryptographic hash function. It explains the concepts and applications of these cryptographic tools in ensuring data security and integrity.
Serge Vaudenay entered at the Ecole Normale Supérieure in 1989 with a major in mathematics. He earned his agrégation (secondary teaching degree) in mathematics in 1992, then a PhD in Computer Science at the University of Paris 7 - Denis Diderot in 1995. He subsequently became a senior research fellow at the CNRS, prior to being granted his habilitation à diriger des recherches (a postdoctoral degree authorizing the recipient to supervise doctoral students). In 1999, he was appointed as a Professor at the EPFL, where he created the Security and Cryptography Laboratory.

This course introduces the basics of cryptography. We review several types of cryptographic primitives, when it is safe to use them and how to select the appropriate security parameters. We detail how
Explores the commitment scheme, key derivation function, and pseudorandom generator in cryptographic protocols, emphasizing their role in ensuring data integrity and authentication.
